Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Collection Container/Tube:

Preferred: 2 serum gel Microtainers

Acceptable: 2 red top Microtainers

Submission Container/Tube: Amber vial (Supply T192)

Specimen Volume: 0.5 mL

Collection Instructions:

1. Protect specimen from light.

2. Serum gel Microtainers should be centrifuged within 2 hours of collection.

3. Red-top Microtainers should be centrifuged and aliquoted within 2 hours of collection.

Additional Information: Patient's age and sex are required.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

0.25 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected


Mild reject; Gross reject
